Digital forensics describes the process of going into a technological device such as a computer or a cellphone in order to monitor the activity on these items and determine if the item has been hacked previously and/or is being watched. You may think that you don’t have much to hide on your technological device, so this warning need not apply to you. But just because you’ve hit a “delete’ button doesn’t mean that a good hacker can’t find a copy of it somewhere on your machine. This field is constantly evolving and adjusting to meet the demand and new technologies released and it is ever growing with the cellular market.
